रङ्गवङ्गे पिचुस्थूलो कूलटी तु मनःशिला यवक्षारश् च पाक्यः स्यात् त्वक्क्षीरा वंशलोचनाः
raṅgavaṅge picusthūlo kūlaṭī tu manaḥśilā yavakṣāraś ca pākyaḥ syāt tvakkṣīrā vaṃśalocanāḥ
ดีบุกและตะกั่วควรใช้ในสภาพเป็นเม็ดหยาบคล้ายปุยสำลี (ปิจุสถูละ); ‘กูลฏี (kūlaṭī)’ และ ‘มะนะห์ศิลา (manaḥśilā)’ หรือเรียลการ์ก็ระบุไว้ด้วย. ‘ยะวะกษาระ (yava-kṣāra)’ ควรเตรียมด้วยการหุง/เผาให้สุก (การคัลซิเนชันหรือสกัด). เช่นเดียวกัน เปลือกไม้ที่มีน้ำยางขาว (tvak-kṣīrā) และ ‘วังศะโลจะนะ (vaṁśa-locana)’ หรือมานนาจากไผ่ ก็เป็นวัตถุที่ใช้ได้.

FAQs
It conveys Ayurvedic/Rasashastra drug-knowledge: specific metals/minerals (tin, lead, realgar), plant-drugs, and a processing directive—barley-alkali (yava-kṣāra) must be prepared by cooking/heating (pākya).
By cataloging pharmacological substances and brief manufacturing notes (like alkali preparation), it shows the Agni Purana functioning as a compendium that includes practical medical and pharmaceutic know-how alongside theology and ritual.
While primarily technical, such correct preparation and use of remedies supports dharma through protection of health and effective, non-harmful practice—right knowledge (yathā-vidhi) is treated as meritorious because it prevents misuse of potent substances.
